Ok but a 256gb SSD (Samsung 850 Evo) can be had for $88 and 240GB Crucial or SanDisk for $64.
That unit does have other embellishments though... like FHD 1920 x 1080 display. vs 1600 x 900 or 1366x768.
the refurb market is an ever changing one, what's not available today may come available next week or next month.
RAM and DISK can easily and cheaply be upgraded. The other components you're not so likely to change.
For $399 they have
Intel Core i5 3320M Dual Core (2.60 GHz)
- Windows 10 Professional 64-Bit
+ $88 = $487. But the display is only 1600 x 900 and you'd have to swap the disk so the other one still isn't a bad deal overall.
Good luck.
